Question

我有一项行动,从<代码>查询获得初专干事数据。表格[0],并输入域名。

我正在测试这一方法,但似乎不可能确定要求。表格。

I could extract the method to another that takes the string it returns, but that would just be a one line method and the Action would still be untested.

是否有办法测试这一或另一种更可测试的方法,以从$.ajax(上查询初等元数据?

Answer 1

有可能通过将<条码>载的参数书写成该方法,将其作为一个参数。

<代码>公开 JsonResult ActionName (string paramName)

并将其列入数据:

var dataVar = getDataVar();
$.ajax({
    url:  /Controller/ActionName 
    , type:  post 
    , data: { paramName: dataVar }
    , dataType:  json 

    , success: function (returnJSON) {
    }
    , error: function (XMLHttpRequest, textStatus, errorThrown) {
    //error handle in here
    }
});

Personally I Use MVCContrib TestHelper to unit test my controller actions. It makes things very fun and easy.

So in your case assuming the following controller (disclaimer: absolutely never write something like this in a real application, it s just an example here, in a real world application controller actions should never fetch stuff from Request.Form, they should use strongly typed action parameters and leave the default model binder do the parsing, etc...):

public class MyViewModel
{
    public string SomeProperty { get; set; }
}

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var json = Request.Form[0];
        var model = new JavaScriptSerializer().Deserialize<MyViewModel>(json);
        return View(model);
    }
}

你们可以检验:

// arrange
var builder = new TestControllerBuilder();
var sut = new HomeController();
builder.InitializeController(sut);
builder.Form.Add("foo", "{ someProperty:  some value  }");

// act
var actual = sut.Index();

// assert
actual
    .AssertViewRendered()
    .WithViewData<MyViewModel>()
    .SomeProperty
    .ShouldEqual("some value", "");
